Product Selection Differences for General Utility Butterfly Valves, Chemical Industry

When selecting butterfly valves for general utility applications versus for the chemical industry, there are several key differences to consider:

1. Material Compatibility: In the chemical industry, it is crucial to choose butterfly valves that are made from materials compatible with the specific chemicals being handled to prevent corrosion or chemical reactions. This could include materials such as stainless steel, PVC, or lined valves with materials like PTFE.

2. Sealing Technology: For the chemical industry, tight sealing is important to prevent leaks and ensure the proper containment of hazardous chemicals. Resilient seat materials like EPDM or Viton may be preferred for chemical applications compared to general utility valves.

3. Pressure and Temperature Ratings: Chemical processes often involve high pressures and temperatures, so selecting butterfly valves that have the appropriate pressure and temperature ratings for the specific chemical environments is critical.

4. Compliance and Certifications: In the chemical industry, valves may need to meet specific industry standards, certifications, or compliance requirements such as API, ANSI, or ISO standards to ensure safety and regulatory compliance.

5. Corrosion Resistance: Chemical environments can be corrosive, so choosing butterfly valves with corrosion-resistant coatings or materials is essential for longevity and reliable performance.

6. Flow Characteristics: Depending on the chemical process, the flow characteristics of the butterfly valve may be important. Consider factors such as flow capacity, pressure drop, and flow control requirements when selecting a valve for chemical applications.

By carefully evaluating these factors and selecting butterfly valves that are specifically designed for the demands of the chemical industry, you can ensure optimal performance, safety, and reliability in your processes.
